| description | Precise PnL calculator for any Polymarket address — reconstructs profit/loss from Data API cashflow (BUY/SELL/REDEEM/MERGE/SPLIT/REBATE) plus unrealized position value. Matches official /profit within ~0.2% MAPE on leaderboard validation. Bring-your-own Python (httpx). |

Polymarket Precise PnL
Compute precise, audit-grade PnL for any Polymarket address via the Data API cashflow method. Unlike position-level approximations used by most profilers, this reconstructs every BUY / SELL / REDEEM / MERGE / SPLIT / REBATE event and reconciles against current unrealized position value.
Validated against Polymarket's official /profit endpoint on the public leaderboard: MAPE ~0.2%, all top accounts within 1% error.
Trigger
Invoke this skill when the user wants:
- Audit-grade PnL for one or more Polymarket addresses
- Bulk PnL over a leaderboard or an address list
- Benchmark mode: compare a local PnL dataset vs. the official /profit values
If the user just wants a quick profile (win rate, positions, category breakdown), use the polymarket-profile skill instead — it's lighter and runs on curl alone.
Requirements
python3 (3.9+)- One Python package:
httpx
Install once:
pip install -r ${SKILL_DIR}/requirements.txt
pip install httpx
${SKILL_DIR} is the path where this skill lives (e.g. ~/.claude/skills/polymarket-pnl/).
Core CLI
All invocations run from the skill directory (or with python3 <skill_dir>/compute_precise_pnl.py):
python3 compute_precise_pnl.py --address 0x63ce342161250d705dc0b16df89036c8e5f9ba9a
python3 compute_precise_pnl.py --leaderboard 50
python3 compute_precise_pnl.py --addresses-file targets.txt
python3 compute_precise_pnl.py --leaderboard 100 \
--benchmark local_pnl.jsonl \
-o precise_vs_local.jsonl
Output is JSONL streamed to --output (default: ./precise_pnl.jsonl).
Output schema
Each line is one address record:
| Field | Type | Meaning |
|---|
address | str | The lowercase 0x proxy wallet |
pnl | float | Trading cashflow PnL (BUY/SELL/REDEEM/MERGE/SPLIT/REBATE + unrealized). Primary metric. |
pnl_inclusive | float | pnl + REWARD + REFERRAL_REWARD + CONVERSION (platform credits) |
total_buy, total_sell, total_redeem, total_merge, total_split, total_rebate, total_reward, total_referral, total_conversion | float | Sum of each activity type |
unrealized | float | Current mark-to-market value of open positions |
open_positions | int | Number of open positions |
trade_count | int | Total BUY + SELL events |
computed_at | int | Unix seconds when record was produced |
complete | bool | True if every paginated activity call returned fully |
pagination_incomplete | bool | True if the Data API's ~10k offset ceiling was hit for at least one activity type |
pagination_incomplete_types | list[str] | None | Which activity types hit the ceiling ("BUY", "SELL", ...) |
Known limitations
- Data API offset ceiling (~10k): extremely high-frequency accounts may hit it on one activity type. The record is still emitted with
pagination_incomplete=True and the field list so you can flag or re-fetch via timestamp-chunked backfill.
- Same-second full-page boundary: the timestamp-based pagination uses
end = oldest - 1 with a heuristic backfill pass that only triggers when the boundary timestamp already appears more than once in the current page. If a full page ends with exactly one row at timestamp T and additional same-second rows continue onto the next page, those rows may be skipped without pagination_incomplete being set. This affects a small subset of very-high-frequency accounts; most addresses stay within 1% of the official /profit. A stricter backfill is on the roadmap.
pnl vs pnl_inclusive choice: Polymarket's official /profit endpoint inconsistently includes platform credits across addresses. The primary pnl field deliberately excludes them so the number is reproducible from public trade data alone.- Requires
httpx: the only third-party dependency, for its robust TLS/HTTP/1.1 handling against the Data API.
- No authentication: uses only public endpoints (
data-api.polymarket.com, gamma-api.polymarket.com), so there are no API keys to manage but also no access to private endpoints.
Comparison with polymarket-profile
| Aspect | polymarket-profile | polymarket-pnl (this skill) |
|---|
| Runtime | curl + jq / node | Python 3 + httpx |
| PnL accuracy | Position-level cashPnL (approximate) | Cashflow reconstruction (~0.2% MAPE) |
| Bulk mode | Single address per call | Single / leaderboard / address list |
| Win rate / categories | ✅ | ❌ (PnL only) |
| Benchmarking | ❌ | ✅ vs local dataset |
| Best for | "Who is this address?" | "What is their audit-grade PnL?" |
Use them together: polymarket-profile for the qualitative picture, polymarket-pnl when the PnL number has to hold up to scrutiny.
Data sources
All public, no authentication required:
| API | What it provides |
|---|
data-api.polymarket.com/activity | BUY / SELL / REDEEM / MERGE / SPLIT / REBATE / REWARD / REFERRAL_REWARD / CONVERSION events |
data-api.polymarket.com/positions | Current open positions, for unrealized value |
data-api.polymarket.com/v1/leaderboard | Ranked addresses with official /profit values |
